and useful Improvements in jUniversal i Joints; and I do declare' thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

My invention relates to universal joints especially adapted for use inconnection with automobiles, and is designed to furnishl a cheap andsimplified construction, of ex treme iexibility and extensibility; inwhich the parts are protected from dust and grit; in which the waste andescape of thelubri'- cant is avoided, and in which the shellor y casingisvutilized to serve as one of the jointmembers. p

To these ends my device consists of the devices, construction andarrangement of parts hereinafter described, and illustrated in theaccompanying drawings, inwhichf Figure 1 is a central transversesectional `plan-view of my device; Fig. 2, an end-ele-v vation ofthesame with the. cap hereinafter referred to,- removed; Fig. 3,"aside-elevation of one of the shaft-members'herein referred to, showingits bearings in the'ring, hereinafter referred to, and Fig. 4, anend-elevation of said shaft-member seen from its outer end.

Likenumerals of reference indicate like parts throughout the drawings.

In the drawings, 1 is a cup-shaped case or shell open at both ends, thelarger opening being lianged as at 2. This opening has a closure 3yhaving therethrough a vcentral shaft-opening 4, the closure beingprovided with a flange 5 corresponding to the ange 2. The two flangesare secured, face to face, by means of boltsand nuts 6. The edge of theopposite, smaller opening 7 is turned inwardly to form a circular groove8 in which is a lubricated packingrringhl. 10 is a plate f the outersurface of which is formed as the segment of a sphere which surface ispressed outwardly against the packing-ring 9 byv means of an internalspring A11 interposed between a shoulder 12 on the drivenshaft 13Appiiationmed March `14; 191'?.v seal in). 154,654...v

Theyinner end lofthei shaft13` cated, the bifurcations terminating intwo nions 14, journaled in bearings 17-17 in a ring 15, This ringconsists of two like ringparts secured together, side by side, by bolts16, the rings having coincident enlargements 1n which are opposedsemi-cylindrical depressions which afford four bearings 17-17 and 18-18disposed at right angles to each other.

In opposite sides of the shell 1 are alined holes 19 having inwardlyturned lips. 20 is a shaft the ends of which fit closely in the holes19, the shaft being held againsty longitudinal andv axial movements bymeans of pins 21 passing through the lips of the holes and through theshaft. Upon the shaft 20 are journaled the two bearings 18--18 formed inthe twopart ring 15.

The part 3-4 is secured rigidly in any preferred manner to a drivingshaft. The shaft-member 13 is internally grooved as at 22 for thereception of a correspondingly splined shaft,-not shown. The outer'endof the shaft-member 13 is provided with a gland 23 which yprevents theescape of lubricant from the interior of the shell around the internalshaft.

It will now be seen that the shell provides protection Afor the bearingsof the de vice against access of grit and dirt; that the twoshaft-members have `a wide range of movement relatively to each other,both anlgularly and longitudinally; that theln-bricant is confined sothat it cannot waste and so that the exterior of the joint can notbe- 1.
